Title: Improved locking circuit and control
IPC: H03K23/82
Filed: 1948-10-13
Abstract: 652,571. Valve circuits. RADIO CORPORATION OF AMERICA. Oct. 15, 1948, No. 26906. Convention date, Oct. 15, 1947. [Class 40 (vi)] In a trigger-pair circuit comprising two crossconnected valves, one of the biassing impedances between control-grid and cathode comprises the anode to cathode impedance of a third valve to the control grid of which the controlling voltages for the trigger-pair are applied. The Figure shows a trigger-pair circuit comprising cross-connected valves V2, V3, the grid circuit impedance of valve V2 comprising the anode to cathode impedance of valve V1 in series with a biassing resistor 6. In the absence of control signals at terminals 9, 91, if valve V3 is conducting and valve V2 cut-off, then the anode voltage of valve V1 is low and there is only a small flow of current through valve VI, so that the anode to cathode impedance has a low value. When a negative-going potential is applied at terminal 9, valve V1 is cut-off and its impedance is increased so that the grid voltage of valve V2 rises and the trigger-pair changes over in the normal manner to its second stable state with valve V2 conducting and V1 cut-off and remains in this state when the voltage at 9 is removed. When a positivegoing voltage is applied at 9, valve V1 conducts so that its impedance is reduced the grid potential of valve V2 falls and the circuit reverts to its initial stable state.

Title: Method of processing thin flat ceramic plates
IPC: H01B1/00
Filed: 1954-09-20
Abstract: <PICT:0773686/III/1> A method of processing thin flat ceramic plates having a thickness small compared to both length and width comprises embedding a plurality of the plates side by side in edge to edge relation in a body of settable material with opposite faces of the plates generally parallel to opposite faces of the body whereby the operations are performed on the plates as a group, and separating the individual ceramic plates from the body.  A plurality of barium titanate plate 1, which may be warped as a result of firing, have cast thereabout a resin 9, such as an unsaturated polyester or an epoxy resin; the resin may contain a filler, e.g. powdered mica.  The opposite faces of the composite body are ground, e.g. in a lapping machine, to produce a disc of required thickness.  Metal paint, e.g. silver paint, is then applied, by squeegee, dipping or spraying, over the entire areas of the faces of the finished disc.  The disc is then fired to complete metallization of the faces; the resin is consumed. Alternatively the disc is preliminarily dried after coating and the coated plates separated from the disc before firing.  For the coating operation only, a cement like material such as plaster of Paris may be cast around the plates instead of resin, the cement disintegrating at the firing temperature of the metal paint.  The metal-coated plates may be used stacked in electrical condensers and back-to-back in piezoelectric devices such as microphones and phonograph pickups.
